This invention relates to a method of oining the ends of wire cloth or fabric, such as is used on paper-making machines, and the principal object of our invention is to provide a method of oining the ends ofthecloth or fabric in such a manner as to obtain amaximum of strength and a minimum drainage obstruction, which is essential for the successful operation under the exacting requirements to which a wire cloth or fabric of this nature is subjected.

A further object is to provide a method of joining the ends of the cloth or fabric in such a manner as to obtain a uniform impervious cloth or fabric atthe point of joining.

A further object is to provide a method of joining the ends of the cloth or fabric in such al'nanner that such joining or uniting is intermediate the top and bottom surface planes of the fabric.

A further object is to provide a method of joining the ends of the cloth or fabric by uniting the protruding ends] of the warp wires of one end of the cloth or fabric, intermediate the marginal weftwires of the respective joined portions, to the opposite end of such cloth or fabric. Q

With thefo-regoing and other objects in view as will appear as the description proceeds, the invention consists in the method ofjoining the ends of wire cloth or fabric as hereinafter more specifically set forth,

claimed and shown in the accompanying drawing forming a part of the present application, in which:

Fig. 1 and Fig. 2 are longitudinal section views of the respective ends of the wire cloth or fabric which are to .be joined, and

Fig. 3 is a longitudinal section view of the respective ends of the wire cloth or fabric showing them as joined, on the line GC.

Like numerals of reference designate corresponding parts throughout the different views.

The first step in our method is to securely unite the warp wires 5 and 6, in their woven position, to the marginal weft wire 4, by soldering, welding, fusing, brazing, or other like manner. After the wires 4, 5 and 6 are united, the protruding ends of the wires 5 and 6 are cut off as on a line AA ofFig. 1 which line of cutting is substantially flush with theouter edge of the marginal wire 4. The next step in our method is to securely unite the warp wires 5 and 6", in their woven position, to the weft wire 7,"which is the next to the marginal weft Wire 8, by soldering, welding, fusing, brazing, or other like a manner. "After the wires 7, 5' and 6" are united, the protruding ends of the wires '5' and 6' are cut ofl as on a line B-B of Fig. 2, which line of cutting is substantially flush with the inner edge of the marginal wire 8. Thus the weft wire 7 becomes the marginal weft Wire of this portion of; fabric.

' The next step in our method is to bring the respective ends of the wire cloth or fabric together, preferably, insuch a manner that the free ends of the warp Wires 5 and 6 abut the ends of the warp wires 5 and 6 as shown on'the line C-C of Fig. 3. While held in such abutted position, these ends are securely united to'provide an integral connection between the respective warp' wires 5-5 and thewe'ft wire f and between the respective warp wires 6,-6" and the weft wire 4, by soldering, welding, fusing. brazing, or other like manner. This provides a'continuity of the wires .5,-5 and '6 6 in uniform woven relationship, with' a minimum drainage obstruction intermediate the weft or,warp wires at the point of joining. We do not wish to, be limited to the warp wires 5" and 6 having to precisely abut their respective warp wires 5 and 6. Theprotruding ends of the warp wires 5 and 6 may abut and contact with the marginal weft wire 4 intermediate the warp wires 5 and 6 either vertically or laterally. f By cutting the portion of'fabric asshown in Fig. 1, on the line A'A where the warp wires5 and 6 are in converging relation to each other; and, by cutting the portion of fabric. as shown inFig. 2, on the line B B, where the warp wires 5" and 6 are in di-Q verging relationship to each other,,the warp wires 5, 6, 5 and 6' are cut on an angle and consequently the abutting faces of such warp wires provide a greaterv area than the normal cross-section area thereof. Furthermore,

the contacting faces thereof are preferably cut in parallel planes and the ends of the warp wires to be joined are intermediate and in spaced relation from the top and bottom surface planes of the respective portions of fabric, when the warp Wires 5 and 5. and 6 and 6 are joined'res'pectively. By joining the respective warp wires, as on the line G-C of Fig. 3 and in the manner as hereinbefore described, the respective contacting warp wires are in direct longitudinal alignment with each other and form an uninterrupted uniform mesh formationat the point' 5 woven warp and weft wires, consisting of cutting the ends: of .the respective sets of wires, forming the'warp wires of one portion, at a point where they are in diverging relationship to each other; cutting the ends of the respective sets of wires, forming, the warp wires of the other portion, at a. point where they are in converging relationship to each other; and uniting said ends, interme diate the marginal weft wires of said portlOl'lS.

A method of joining the ends of portions of wire cloth or fabric, composed of woven warp and weft wires, consisting. of positioning the respective joining ends of the warp wires of said portions in direct longitudinal alignment with eachother; and uniting said ends, intermediate and in spaced relationship from the surface planes of said portions.

5. A- method of joining the ends of portions of wire cloth or fabric, formed'from 'portions woven of warp and weft wires; consisting of cutting the endsof the respective sets of wires forming the warp wires of one ortion at a point where they are in diverg-.

1ng relationship to each other; cutting the ends of the respective :sets of wires; forming the warp wires of the other portion at a'point where they. are inconverging relationship to each other and uniting the ends of said .portions-intermediate the marginal, Weft wires of said portions, together in a pervious structural formation substantially uniform with the pervious structural formation of said portions.
